LEON J. CAMPBELL, OF CHICAGO, ILLINOIS.

' SEAL-LOCK.

Application filed- Febr'uary 3,v 1910.

To all whom it may concern:

Be it known that I, LEON J. CAMPBELL, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Seal- Locks, of which the following is a specification.

My invention relates to seal locks, and its object is to provide a device of that character which shall be simple and economical in construction and effective in operation.

This object is attained by, and my present invention is embodied in, the following described mechanism, illustrated by the accompanying drawings, in which Figure 1 is a perspective view of a receptacle or chest to which my seal lock is applied; Fig. 2 is a like view of the latch portion of my lock, a part of the shank being broken away; Fig. 3 is a like view of the keeper portion of my lock, a part of the plate whereby it is attached to the receptacle being broken away; Fig. 4 is a plan view of my lock, with broken parts of the chest and its door showing attachments of my lock thereto; Fig. 5 is a sectional view of the same parts on line 55 of Fig. 4, and also a sectional view of the seal; Fig. 6 is the same, but showing the seal applied to lock the device; and Fig. 7 represents a portion of Fig. 6 and illustrates the means for removing the seal to unlock the device.

A projection or lug 1 of the latch 14, having a shank 2 by which it is attached to the door or lid 3 of any receptacle, as the chest 4, is adapted to enter when the door is closed into a socket 5 in the keeper 6 which is fastened to the body of the receptacle. This socket has an overhanging or inwardly-extending flange 7 a short distance above the face of the lug when it is in its operative position in the socket. A longitudinal slot 8 in the wall of the socket admits the shank of the latch, and extends to the bottom of the socket, so that the socket may readily be kept clean of dirt and water. A groove 9 in the latch registers with the under side of the flange when the lug is in operative position, whereupon an edgewise-extensible seal, preferably the concavo-convex seal 10 of suitable thin material, as tin, is inserted, concave side inwardly, into the mouth of the socket, and is then flattened out on the face of the lug by a blow, so that its edges are forced into the groove and under the flange all around,

thus holding the latch in its operative posi tion and looking or sealing the device. Characters of identification may be impressed on the seal as shown in Fig. 4, and the seal may be removed to open the receptacle by thrusting an instrument, as the hook 11, through the seal and into a suitable pit 12 in the face of the lug and then withdrawing the hook, carrying the seal with it. The walls of the socket are adapted to enter a suitable recess 18 in the door when it is closed so that no part of my seal lock will project from the sides or the top of the closed chest it will be seen that my entire lock is thus protected from injury, and that chests equipped therewith may be piled on each other and close together without intervening space.

Not confining myself to the details of construction shown and described further than as set forth in the claims, I claim:

1. In a device of the character described; a keeper having a socket with an overhanging flange; a latch having a lug adapted to enter the socket through the internal wall of the flange; and a seal adapted to be inserted into the socket over the lug and to be then forced under the flange to hold the lug and latch in operative position.

2. In a device of the character described; a latch having a lug and a groove; a keeper having a socket adapted to receive the lug and provided with an overhanging flange whose bottom registers with the groove when the lug is in its operative position; and a seal adapted to be inserted into the socket over the lug and to be then forced into the groove and under the flange.

3. In a device of the character described; a latch having a lug and a shank; a keeper having a socket adapted to receive the lug and provided with an overhanging flange and having a longitudinal slot in the wall of the socket adapted to receive the shank; and a seal adapted to be inserted into the socket over the lug and to be then forced under the flange.

4. In a device of the character described; a latch having a lug, a shank and a groove; a keeper having a socket adapted to receive the lug and provided with an overhanging flange whose bottom registers with the groove when the lug is in its operative position, and having also a longitudinal slot in the wall of the socket adapted to receive the shank; and a seal adapted to be inserted into the socket overthe face of the lug and to be then forced into the groove and under the flange.

5. In a device of the character described;

5 a receptacle, a keeper on the receptacle having a socket provided with an overhanging flange; a door on the receptacle having a recess adapted to receive the walls of the socket when the door is closed, and having a 10 latch provided with a lug adapted to enter the socket; and a seal adapted to be inserted into the socket over the lug and to be then forced under the flange. I

In Witness whereof, I have signed my name to this specification in the presence of 15 two subscribing witnesses.
